[Gambas-user] SMTP Client errors - Sending Email

[Marty]

God Morning All,

I'm using gb.smpt to send email from a Gambas routine. The routine is:

12 Public Sub btnSend_Click()
13
14  Dim t$ As String
15      Dim email As New SmtpClient
16
17      t$ = File.Load("/home/marty/Test.txt")
18
19      With email
20        .Add("Hello")
21        .Add(t$, Mime.Default, "Test.txt")
22        .To.Add("xxxxxx at ...3172...")
23        .From = "xxxxxx at ...3172..."
24        .Subject = "Linux Test"
25        .Encrypt = Net.SSL
26        .Port = 465
27        .Host = "smtp.xxxx.com"
28        .User = "xxxxxxx at ...3172..."
29        .Password = "password"
30        .Debug = True
31     End With
32
33      email.Send()

End

Sensitive data removed. There are multiple errors:

1. If I include the line to add an attachment -"Cannot find Mime subtype 
in line 33"

2.If I use Net.SSL with port 465  "Error 535 Authentication failed"
     My account should use SSL and port 465. That's the way it is set up 
on Windows.
     Debug output:
<- 220 relay01.dlls.pa.xxxxxxx.net ESMTP Postfix

-> ehlo marty-xxxxxxxxxxxxxxxxxxxx

<- 250-relay01.dlls.pa.xxxxx.net
250-PIPELINING
250-SIZE 36350634
250-ETRN
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

-> auth plain AG1tY2cyOTQ0MEBmcm9udGllci5jb20AOTA2NlBvDQo=

<- 535 5.7.8 Error: authentication failed: authentication failure

-> quit

No matter what I try the message is not sent. The docs say that V 3.4 
supports encryption.
Can you  tell me where I'm going wrong? I'm running Ubuntu 12.04. Is it 
possible that SSL is not installed? How can I check it? Then how to 
install it?

Thanks for your patience and help!

Marty
